ATTACHMENT FOR TRACTOBS AND MOTOR VEHCLES.

Application filed July 23, 1921. Serial No. 486,949.

To asZZ whom t may concern Be it known that I, ALFRED W.l KNUTsoN, acitizen of the United States, a resident of Galesburg, in the county ofKnox and State of Illinois, have invented new and useful Improvements inAttachments for Tractors and Motor Vehicles, of which the following is aspecification.

This invention has reference to an attachment for tractors and motorvehicles, and particularly to such asv Vmay be provided with a rein orline control, as supplemental to the usual and ordinary controllingmeans therefor.

The invention has for its principal object to improve the attachmentdisclosed in my application (C) iiled November 20th, 1920, bearingSerial No. 425,462, which is closely associated with and a companion toapplications (A) and (B) bearing Serial Nos. 425,460 and 425,461respectively.

The object, as stated in application bearing Serial No. 425,462, is toprovide a self contained attachment, which is formed for b-odilysecurement, to a tractor or like vehicle, and which includes rein orline control means for the fuel feed regulating device; such contro-lbeing capable of advancing such fuel feed as may be required when thegear shifting has been accomplished to set the tractor in motion, andfrom time to time as may be needed when the tractor is under heavy load,such for instance as when taking an incline or meeting unusualobstacles, and for retarding the fuel feed when ground conditions arenormal and when slowing the tractor down and stopping.

While the present attachment is applicable to the clutch lever of atractor of the type of the Fordsom and under the con- -trol of theoperator or attend-ant through the pro-vision of reins or lines, inaddition to permitting freedom of use of said lever 1n the ordinarymanner, by foot operation; it is to be understood that the presentattachment may be found equally as applicable to other and differentmakes of tractors where a fuel feed regulating device may be used.

That the invention may be more fully understood,`reference is had to theaccompanying drawings forming a part of the present description,illustrating a preferred embodiment of the invention, in which Fig. l isa-detail Vside elevation of so much of an attachment, as is necessary toillus-A trate the within invention;

Fig. 2 is a detail sectional view as the same would appear on the line2%-2 of Fig. 1, except that the position of parts has been changed, and

F ig. 3 is a detail elevation of in F ig. 2.

Like characters of reference denote corresponding parts throughout thefigures.

VFor the purposes of this disclosure the gear shifting lever isdesignated D, the clutch lever is designated H, and 100 designatesgenerally the fuel feed regulator controlling means including theoperating rod J controlled through and by means of a lever arm, notshown, at the steering wheel of the tractor. l am not here concernedwith the detail construction of the component elements of the fuel feedregulator controllingl means, as that disclosed in application bearingSerial No. 425,462 will sufce, or the same may be some other or modiedconstruction, except that an arm or bar lll or its equivalent is theinstrumentality through which motion is imparted from my attachment tothe operative parts constituting such fuel feed regulator controllingmeans. l

ln my attachment and in my application bearing Serial No. 425,462 across-shaft 63 is employed arranged to be operated by a segment 6l fromand by means of reins or lines, not shown, and a connection is madebetween the shaft 63 and the arm or bar lll, by means of a double endedcrank arm 87 connected to one end of said shaft 63.v

parts seen Referring now to the attachment conneci tion between theclutch lever H and the shaft 68, 1 denotes an inverted U shaped clampwhich is dropped `down over the clutch lever and same preferably held bya cot-ter pin 2v orsome other suitable means. Said clamp is providedwithan angle plate 3 having an opening 4 therein, through Vwhich ispassed the Ystem or rod 5 threaded thereto a head 9. Normally/the flange-1s .located immediately under or juxtaposition to the lower end of thehousing 7, best seen in Figs. l and 3', withthe head 9 of the stem orrod 5 removed somewhat above the f upger end of said housing 7 thellowerend of the housing 7 and against the inside of the upper end o-f saidbarrellike casting, see Fig. 2. 'This spring normally holds thebarrel-like'casting at the upper end of the housing 7, as seen in Fig.2, and said barrel-like casting is preferably held againstfoscillatorymotion .by means of the guide fingers 12 connected thereto andlocated'on opposite sides of said housing 7, as best seen in Figs. 2and' 3.

The double ended crank arm 87 which is connected to one end of the shaft63, as shown in Fig. 1,'has one end pivotallyconuected with the slottedlower end off the arm or Vbar 1-1-1, while the oppositeend of said crankarm is pivotally connected to said barrel-like casting l0 somewhat inthe manner shown in Fig. 2; that is to say, said lirank arm has aconnection with said barrellilre casting through and by means of a pivotpin 13, the inner head of which is fitted in a socket 14 in thebarrel-like casting so that there may be some play between the crank arm87 and said casting tol provide.

for irregular castings and crudeness in assemblage ofthe elements, orparts ofthe device so as not toI cramp the movement of the barrel-likecasting ywhen the crank arm 87 is actuated'thro'ugh the shaft 63 torecipe rocatevsaid barrel-like casting within and independently vof thehousing -7 land with said housing In operation, assuming that a Vtractoris equipped with the fuel feed regulator controllingf means shown and.described in my application bearing Serial No. 425,462, or

so-me other similar or equivalent'means and it is desired to actuatethesame in the usual andV ordinary manner provided on tractors, and Inotby rein or line control means, when theV operator or attendant depressesthe clutch lever H it may oscillate and -pull down with it, the stem orrod. 5 which will move from the-dotted line position in Fig.

2 to the full line position therein shown in said figure, withoutoperatingthe parts of the attachmentother than theclarnp ,l con-V nectedto said clutch lever. Vz This construction ofthe stem or rod 5 Aanditsrelation'to the housing 7 so that it will be reciprocated thereinwithout-movement of the. barrel-like casting 10, will, asV understood,allow the clutch lever H to be actuated by the foot in theordinary andusualmanner.

Assuming that therein or line means parting movement to the fuel feedregulator controlling Vmeans 'forthefpurpose of Yad- Y vancingV orretarding the gas, the slight .oscillation in'xparted tocthe crank arm87 will depress the v,barrel-like casting l0 with- Y in the housing 7,.against the tension of the spring 1.1, said spring, with eachactuationV of the shaft 63, returning .the barrel-like casting 10 andthe crank arml 87 to a position similar to that shown in Fig. l, andsuchoperation in no way affects the operationof the clutch lever H, aswill be yunderstood. Now, when theactuation of the fuel feed regulatorcontrolling means slightly precedes that of the' clutch lever H, andwhen a long pull is made upon the reiner lines `,to operate the shaft 63to the limit of its movement, the reciprocation ofthe barrel-lilrecasting 10 through the oscillation ofthe crank arm v8,7 will force said`barrellike casting l() into engagement with the lower end of thehousing 7 and it .bearing will reciprocate the latter, ,and `it beingconf `nected with the clamp l, willas will`be understood, reciprocatethe clutch lever H,

moving it from the position shown in full lines in Fig. lt@ the dottedline-position in said figure It is understood thatV the fuel Yfeedregulator controlling means may be yactuated Vto retard or advance .thegas at all times without actuating` the clutch and that a full actuationof theshaft 63, which y will carry the barrel-like casting l0 throughto. the limit of .its reciprocalk movement, will also Aimpart movementto the clutch lever H for the purposes usual in devices of thischaracter and substantially in themanner and for the purposes described,by the attachment in the application above re? ferred to, bearing SerialNo. 425,462, of

which the herein described attachment is an improvement.

It is to be notedthat the tension in 4the springll is considerably lessthan the tension in the spring, not shown, associated in the usualmanner with the clutch lever H,

and therefore, while the barrel-like casting 10 may bedepressed or moveddownwardly a limited distance vagainst the tension of said spring 1l,and he returned `by such springto its uppermost position, the clutchlever is not disturbed, and not until Vthe casting l() abuts with the'lewe/.rend ofthe housing 7 `and the'pressure ojn the casting iscontinued, is there anymovementdownward of the clutch` lever.. `V
